New Paper Quantifies 15 Years Of Economic And Environmental Benefits From Using Biotech-gm Crops In Colombia
Highlights in the peer reviewed paper include: About 1 million hectares have been planted to cotton and maize containing GM traits in Colombia since 2003 and in 2018, the technology was used on the equivalent of 90% and 36% respectively of the total cotton and (commercial) maize crops. Use of this technology has enabled Colombian farmers to obtain higher yields from better pest and weed control (+30.2% from using stacked - herbicide tolerant and insect resistant cotton and +17.4% from using stacked maize). The extra production and reduced cost of pest and weed control have provided maize farmers with higher incomes equal to an average of US $294/ha and an average return on investment equal to +US $5.25 for each extra US $1 spent on GM maize seed relative to conventional seed. For cotton farmers, the average increase in income has been + US $358/ha, with an average return on investment equal to +US $3.09 for each extra US $1 spent on GM seed relative to conventional seed. Farm incomes have increased by a total of just over US $300 million since 2003. The cotton and maize seed technology have reduced insecticide and herbicide spraying by 779,400 kg of active ingredient (-19%) and, as a result, decreased the environmental impact associated with herbicide and insecticide use on these crops (as measured by the indicator, the Environmental Impact Quotient (EIQ)) by 26%. The technology has also facilitated cuts in fuel use, resulting in a reduction in the release of greenhouse gas emissions from the GM cotton and maize cropping area and contributed to saving scarce land resources.
